Reliable IWLAN radio networks for indoor and outdoor areas
  Two new access point lines for industrial wireless LANs (IWLAN) are now available from Siemens Automation and Drives (A&D). The devices in the Scalance W-786 family are particularly suitable for installation in outdoor radio networks, for instance in public areas, mass transit systems, ports, offshore equipment, or container logistics. With its compact, space saving design, the Scalance W-784 line is specifically targeted at indoor radio networks and can be installed, for example, in a control cabinet or directly in a machine. A&D also has a series of new client modules for integrating one or more nodes in an IWLAN radio network.
Scalance W-786 access points are particularly suitable for applications with high climatic requirements such as in outdoor networks. These scalable products can be supplied in several variants from a single radio card and two antennas to three radio cards and six antennas. Variants with internal antennas, designed for temperatures from -40¡ãC to +70¡ãC, are sufficiently robust to withstand even the most problematic environments. They are insensitive to UV and salt spray, and accommodated in a rugged plastic housing that is resistant to both impact and crushing. No additional mechanical protection is required because there are no external parts that are capable of destruction. Scalance W786-1PRO has one integrated radio card and is offered with two internal antennas or sockets for external antennas. Scalance W786-2PRO has two integrated radio cards and is offered with four internal antennas or sockets for external antennas. Scalance W786-3PRO has three integrated radio cards and sockets for external antennas. Variants with an RJ45 or optical fiber connector are available for connection to a wired Ethernet..
With its compact, space saving design, the Scalance W-784 line is specifically targeted at indoor networks and can be installed, for example, in a control cabinet or directly in a machine. The aluminum housing of the access points conforms to IP30 and affords adequate protection against mechanical stresses or electromagnetic interference. The Scalance W784-1RR variant provides extended functionality, including iPCF (industrial Point Coordinated Function) mode. This optimized access method can be used to implement applications that demand realtime communication and predictable, deterministic response times.
The new range of IP30 client modules integrates one or more nodes in an IWLAN radio network. Scalance W744-1 establishes a radio link between one mobile unit with an Ethernet interface and a radio network. Scalance W746-1 manages the radio link for up to eight connected devices with an Ethernet interface. The module automatically detects a device that has been replaced and manages the new address. Scalance W747-1 differs from the W746-1 module with regard to the rapid roaming function. This provides realtime radio communication even if the nodes cross radio cell boundaries.

New entry-level power supplies for stabilized industrial supply
Siemens Automation and Drives (A&D) is supplementing its Sitop power supplies with a new range of stabilized units for the low-end performance range.
The four new, primary switched-mode Sitop PSA 100E power packs with 230-volt connection and rated output currents of 2.5, 4, 6 and 12 amps meet the basic requirements of the industrial environment. These include the generously dimensioned voltage range from 187 to 264 V AC, the precisely stabilized output voltage, extensive protection functions against overload, and the compensation of voltage drops on long lines. The output voltage can be set between 23 and 26 volts for this purpose.
With an MTBF (mean time between failures) value of more than a million hours, the new Sitop PSA 100E power packs are especially reliable and have a particularly long service life. The fan-free devices are suitable for ambient temperatures up to +70 degrees Celsius, and the efficiency level of up to 90 percent generates low heat loss. The compact metal housing can be snapped onto DIN mounting rails or it can be fixed with screws flexibly on three sides. The removable terminals simplify wiring before installation. The new devices can be used in many sectors and countries and have approvals in accordance with cULus, CB-Scheme and European directives.

Compact thin clients for human machine interfacing in a client-server structure
The new Simatic Thin Clients from Siemens Automation and Drives (A&D) are used as compact terminals for the visualization and input of data. The thin clients are connected over Ethernet with a server on which the application software for human machine interfacing runs. The rugged, hard-disk-free and fan-free devices in degree of protection IP 54 are suitable for all applications with more than one operator station. They are available in 10" and 15" TFT display versions with 64K colors and touch screen operation.
The new Simatic Thin Clients offer a high degree of vibration immunity and have a USB port for connecting an external keyboard or mouse. They are optionally available in degree of protection IP 65. Startup is simple: The thin client requires only an IP address and a host device such as a Simatic Panel, a PC or a server, with which it is to communicate. Connection to the host takes place via the integral Ethernet interface. No other installations are required. Administration and maintenance costs only arise centrally at the server since the applications are not installed on the thin client.
The thin clients can be connected to any servers with the Microsoft standard Remote Desktop Protocol (RDP), and to the Simatic WinCC flexible process visualization system or Simatic HMI Panels using the Sm@rtAccess software. Both connection facilities are installed onboard as standard. The thin clients also enable Web access to HTML pages. Other applications such as office applications like MS Excel or SAP can be viewed and operated via the terminal services of the RDP.

Graded Industrial Ethernet switches for diverse applications
Siemens Automation and Drives (A&D) has developed an entire range of new Industrial Ethernet switches. The new Scalance X-300 product line consists of compact switches that offer functions from the IT area as well as having properties for industrial use. The primary area of application is found in high-performance plant networks with connection to a corporate network via Gigabit Ethernet. The new switches of the product families Scalance X-100 and Scalance X-200 are now equipped with a high port density of up to 24 RJ-45 ports per module. They are suitable for setting up Industrial Ethernet networks with data rates of 10/100 megabits/second, and they have a rugged metal housing for space-saving installation in the control cabinet. In addition, the X-200 switches have an integral redundancy management function.
By means of an integral redundancy manager, the new Scalance X-300 product line offers high-speed media redundancy even for large networks. The switches support IT standards and are suitable for establishing virtual networks (VLANs). They learn multicast sources and destinations autonomously (IGMP Internet Group Management Protocol Snooping), and thus filter multicast data traffic and limit the load on the network. The rugged metal housing in the dimensions of the Simatic S7-300 controller enables space-saving installation on standard mounting rails, S7-300 mounting rails or direct on the wall in different mounting positions. The devices have Profinet diagnostics, SNMP access, integral Web server and automatic e-mail transmission for remote diagnostics and signaling over the network.
The new Scalance X-100 devices are "unmanaged" switches that have a redundant power supply and on-site diagnostics using LEDs. The Scalance X-200 and 300 product series are "managed" Industrial Ethernet switches for space-saving installation in the control cabinet. In conjunction with an IE FC RJ45 Plug, the integral retaining collars provide the sockets of the switches with strain and bending relief. The switches have a redundant voltage supply and a fault signaling contact. On-site diagnostics is carried out using LEDs. The Scalance X-200 and X-300 devices can be integrated into network management systems via SNMP. In addition, the devices are accessed for diagnostics purposes via a Web browser. As Profinet-IO devices, the X-200 and X-300 products can be easily integrated into the configuration and system diagnostics of Step7. The redundancy manager function now built into the X-200 switches enables the establishment of high-speed redundant ring structures.

2-wire 25 Ghz radar level transmitter offers easy installation
Siemens Automation and Drives (A&D) has designed its new radar level transmitter Sitrans LR250 with new Process Intelligence advanced signal processing. The plug-and-play compact 25 GHz 2-wire device is the easiest to install and quickest to configure radar transmitter available today. The level of liquids or slurries can be accurately and reliably measured in minutes. The new transmitter can be used in general applications, but is also suitable for chemical, pharmaceutical and hydrocarbon processing applications, including corrosive environments.
The compact horn allows installation in small openings and the concentrated high frequency beam ensures interference from vessel walls is minimal. A high frequency and narrow transmission pulse means the complete vessel capacity can be measured.
The multilingual Quick Start Wizard guides you to program the transmitter using a few parameters, and has the Sitrans LR250 measuring in minutes. The transmitter can be programmed via the intrinsically safe infrared handheld programmer or remotely using Simatic PDM without opening the lid of the device, thus preventing exposure of the electronics to aggressive atmospheres. The new graphical local user interface (LUI) displays echo profiles and diagnostic information allowing the user to determine dynamics in the tank at a glance. The Sitrans LR250 includes self-diagnostic features that are communicated to the local display and across networks. For example, a timer can be preset to alert the user of a required maintenance or a scheduled quality check.
The new 'Process Intelligence' signal processing evaluates dynamic echo signals. It applies algorithms (based on field data collected from over one million level measurement applications) to raw echoes to produce accurate and reliable level measurement readings. It can automatically ignore obstructions and is the processor behind the more advanced features such as diagnostic tools, Quick Start Wizard and Auto False-Echo Suppression. It also contains a new algorithm that improves the measurement accuracy in the low level of vessels containing low dielectric media.
